RS-422/485 universal PCI card
Staff -- Test & Measurement World, 2/1/2006
Built to work with both 3.3-V and 5-V PCI bus systems, the PCI-1622CU PCI card supplies eight RS-422/485 ports for communication with up to 32 devices. In RS-485 half-duplex mode, only two wires are needed to transmit and receive data. The PCI-1622CU automatically senses the direction of the data flow and switches the transmission direction. No handshaking is necessary, and control is completely transparent to the user. The card's surge protection shields the host system from abrupt high voltages up to 2500 VDC.
